“My fear is this is the playbook of a lot of our brothers and sisters on the left — they’re going to get fringier and fringier, louder and louder, angrier and angrier, and as you and I know, we sometimes have some folks in our society who aren’t completely healthy,” he said.

Schweikert also cited the shooting of House Minority Whip Steve Scalise last year at the Republican team’s practice for the Congressional Baseball Game by a man who was a supporter of Sen. Bernie Sanders.

“We’re supposed to debate, we’re supposed to argue, and we can be passionate, but then we go vote and we have elections, and after we have winners we kind of step back and let them govern,” Duffy said.

Schweikert’s assertion also comes as two member of the Trump administration, adviser Stephen Miller and Homeland Security Secretary Kirstjen Nielsen, were heckled at restaurants and White House Press Secretary Sarah Huckabee Sanders was denied service at another during tensions over the administration’s migrant family separation policy.

“There’s an absolute attempt to dehumanize anyone who disagrees, and particularly the rage is off the charts right now because our philosophy is actually working,” Schweikert said.

“We cannot forget that President Trump, as a candidate, encouraged his supporters to beat up his detractors at rallies, and, as president, morally equated white supremacists with anti-racist activists and encouraged police officers to beat up suspects,” his statement said.
